Vertical navigation
I'd hope most pilots plan their (horizontal) routes with some reference to their experience levels and the equipment fit in their aircraft. IF inexperienced an only using a compass, perhaps it might be batter to leave a wider margin around controlled airspace than if experienced and able to use GPS/Radio Navigation.
But it's my experience that vertical navigation is not taught well at the PPL level, and indeed I still struggle with a conventional PLOG finding the space to indicate level changes when these are need to avoid controlled airspace. I've tried with map annotations (in increasing amounts of red INK) but this still doesn't leave me feeling that I definitely won't bust controlled airspace. I'm still in search of a better PLOG format for vertical navigation...
Does anyone use VORs to setup a "do not cross" line on their chart, as a way of making sure you are clear of controlled airspace?
